Appeal No. 1997-1162
Application 08/200,455
This is a decision on appeal under 35 U.S.C. § 134 from
the final rejection of claims 11-19.
We reverse.
BACKGROUND
The disclosed invention is directed to a disk drive unit
in a magnetic disk unit in which the outer races of ball
bearing units are formed in a one-piece sleeve-rotor structure
to facilitate assembly and to reduce manufacturing costs. The
specification discloses both fixed spindle drives (where the
spindle is stationary and the rotor rotates around the
spindle, e.g., figure 4) and rotary spindle drives (where the
spindle is fixed on the rotor, e.g., figure 3). Only the
fixed spindle embodiment is claimed. The specification also
discloses two different configurations for the stator (yoke)
and the magnets which form the motor drive: an inner-rotor
type (where the magnets are mounted on the rotor
concentrically inside the stator, e.g., figure 4) and an
outer-rotor type (where the magnets are mounted on the rotor
concentrically outside the stator, e.g., figure 2). Both
configurations are claimed.
Claim 11 is reproduced below.
